In the cross performed by Morgan on Drosophila between yellow-bodied, white-eyed females and brown-bodied, red-eyed males it was observed in F₂ generation that the percentage of progenies having parental characters was 98.7% and the percentage of progenies having recombinant characters is 1.3%. What can we conclude from this cross?

detailed solution

Correct option is C

In the cross performed by Morgan on Drosophila between yellow-bodied, white-eyed females and brown-bodied, red-eyed males it was observed in F2 generation that the percentage of progenies having parental characters was 98.7% and the percentage of progenies having recombinant characters is 1.3%. Morgan and his group also found that when genes were grouped on the same chromosome, some genes were very tightly linked (showed very low recombination). Hence, we can say that the genes for eye colour and body colour and body colour are located on same chromosome and are tightly linked.
